Sea to Sky Highway

"I kept pulling over for waterfalls I hadn't planned on, and by Squamish I'd given up on making good time."

The cliffside corridor linking Vancouver to Whistler, where Howe Sound falls away below the road and waterfalls interrupt the drive every few kilometres.

The Sea to Sky Highway is the rare road trip where the road itself is the destination rather than the thing connecting two destinations, and I say that having gone in expecting Whistler to be the point. Highway 99 runs north out of Vancouver along the edge of Howe Sound, clinging to cliffs blasted directly out of the coastal mountains, the water dropping away in sheer drops on one side while granite walls rise on the other. It was rebuilt substantially ahead of the 2010 Winter Olympics, and it shows — wide, well-engineered, genuinely one of the more spectacular short drives I’ve done anywhere, and I include several Alpine passes in that comparison.

Waterfalls on a Schedule You Didn’t Plan

What I hadn’t anticipated was how frequently the highway simply interrupts itself with waterfalls. Shannon Falls, just south of Squamish, drops 335 metres down a granite face visible almost directly from the parking lot — the third-highest waterfall in the province, and one you can be standing beneath fifteen minutes after leaving Vancouver traffic behind. I pulled in intending a quick photo and stayed forty minutes, working my way up the short forested trail to a viewpoint where the spray drifted over ferns and moss in a way that felt more rainforest than roadside attraction. Further north, past Whistler, Brandywine Falls does something similar but more dramatically vertical — a sheer 70-metre drop into a plunge pool ringed by columnar basalt, viewable from a platform close enough that the sound replaces conversation entirely.

Squamish, Between Two Identities

Squamish sits at the halfway point, at the head of Howe Sound, and has clearly spent the last two decades figuring out what it wants to be — a former logging and rail town increasingly overtaken by climbers drawn to the Stawamus Chief, a granite monolith looming directly behind the town that ranks among the largest in the world. I watched climbers working routes on its face from a picnic table in town, craning my neck the way tourists do, while actual locals walked past without looking up at all, which told me everything about how normalized this scenery has become for people who live here. The Sea to Sky Gondola, just outside town, takes the effort out of the view — a ride up to a suspension bridge and viewpoint over Howe Sound that, on a clear day, stretches out toward the open Pacific.

By the time the road climbs properly into the mountains toward Whistler, the character shifts again — sound falls away, alpine forest closes in, and the highway starts behaving like a mountain pass rather than a coastal cliff road. Both halves are worth the drive on their own merits.

When to go: Late spring through early autumn for full waterfall flow and clear Howe Sound views, though the highway is maintained and driveable year-round — winter brings its own appeal as the direct route to Whistler’s ski season.
